Jim Henson's Muppet Babies, commonly known by the shortened title Muppet Babies, is an American animated television series that aired from September 15, 1984 to November 2, 1991 on CBS. The show portrays childhood versions of the Muppets living together in a nursery under the care of a human woman called Nanny (the whereabouts of their parents are never addressed). Nanny appears in almost every episode, but her face is never shown, only the babies' view of her pink skirt and purple sweater as well as her distinctive green and white striped socks. The idea of presenting the Muppets as children first appeared in a dream sequence in The Muppets Take Manhattan, released two months before Muppet Babies debuted, in which Miss Piggy imagined what it would be like if she and Kermit the Frog had grown up together.

The Muppet Babies live in a large nursery watched over by Nanny, who is seen only from the shoulders down. The babies' imaginary games transition from the nursery into scenes that become "real" to the babies, such as finding themselves aboard a pirate ship or in the land of Oz. Often these fantasies are filled with stock footage scenes or live-action clips from popular movies such as Star Wars, Ghostbusters, and Indiana Jones. Each episode contains a related musical number. When the pretend game becomes too perilous, or when an interruption occurs (often in the form of Nanny checking in or the imaginary game straying too far from its original premise), the scene dissolves and they find themselves in the nursery once more.

The central idea of each episode is the power of imagination. Sometimes the babies use their imagination to solve a problem (when Nanny's newspaper is accidentally ruined, the babies write their own newspaper to replace it), but occasionally their imaginations run away with them (overhearing Nanny's phone call to the garbage collector leads the babies to fear that Fozzie is going to be thrown away). Other frequent themes involve the babies coming up with new ways to play with old toys, imagining what life will be like when they are adults, or facing common childhood firsts such as a visit to the dentist or a new addition to the family. Nanny is the voice of reason, congratulating them on their creativity or soothing their fears.

Several Muppets made guest appearances including Janice, and Kermit's nephew, Robin, a young tadpole.

The Muppet Baby character Skeeter, Scooter's twin sister, only appeared in this series, and was never a live-action Muppet. This was done because the producers wanted another female character added to the cast. Despite this, Skeeter was always voiced by a male actor (first Howie Mandel, and later Frank Welker).

In 1984, The Muppets Take Manhattan, the third full-length Muppet film, debuted. The film included a fantasy sequence in which Miss Piggy imagined what growing up with Kermit would have been like. While Piggy sang, baby versions of Rowlf, Fozzie, Scooter, and Gonzo acted as backup singers. The live-action sequence was so successful that The Jim Henson Company turned the idea into a half-hour cartoon program. In order for 107 episodes to be produced, Henson and Marvel hired two companies: the Japanese-based Toei Animation for Seasons 1–3 and five episodes of Season 4, and the Korean-based AKOM Productions for Episode six of Season 4 through Season 7, both of which also animated G.I. Joe and The Transformers for Marvel Productions and Sunbow Productions.

Muppet Babies proved highly popular and ran on CBS from 1984 to 1991, a total of seven seasons. At the height of its popularity it ran in two or three episode blocks.

For a brief run in the second season, the program became Muppets, Babies & Monsters, and a second half-hour was dedicated to a new show called Jim Henson's Little Muppet Monsters. This show featured live action puppets and cartoons starring the adult Muppet characters. The program lasted three weeks before Jim Henson pulled the plug, despite 18 episodes having been made. The show then reverted to an hour of Muppet Babies; however, a portion of the Little Muppet Monsters theme could still be heard in the show's end credits for the remainder of its run. Muppet Babies later expanded to 90 minutes after CBS pulled The Garbage Pail Kids before it even aired due to controversy.

Muppet Babies entered local syndication in 1989, through Hasbro's television distribution unit Claster Television, Inc.. The series ran on local stations until 1992, often on affiliates of the new Fox Network. Syndication rights were sold to Nickelodeon/Nick Jr. (1992–1998) and Odyssey Network (1999–2000) in the US with only 96 episodes in regular rotation. In the United Kingdom, it aired in reruns on Playhouse Disney UK, Disney Channel UK, Toon Disney UK, and Disney Cinemagic, with all 107 episodes in regular rotation. In the UK, it is best known from its first run on UK TV on BBC 1 on Saturday mornings during Going Live! at 8:15am. The show also aired on Network Ten in Australia. In reruns on Nickelodeon and Odyssey Network, the intro was truncated and the 1984 closing was replaced with the 1985 closing.

Approximately 100 of the songs were co-written by Alan O'Day and Janis Liebhart, with the exception of the theme song and Rocket To The Stars which were written by Hank Saroyan and Rob Walsh, and Dream for Your Inspiration, written by Scott Brownlee. The song that played during the end credits was laughingly titled "Hank in the Box" in deference to Hank Saroyan.

In the mid-1980s PVC Muppet Babies toys were available as prizes in McDonald's' Happy Meals. Each non-articulated character came with a wheeled vehicle. Some time later, special Christmas stuffed versions of the Muppet Babies were available in Happy Meals, too.

In 1992, after the last aired Muppet Babies episode in 1991, an episode book collection of Muppet Babies was produced from the book company Grolier. It was called The Muppet Babies Press Books. The book talked mostly about character traits and learning for young children. It was produced and ended in 1992.

There were two Muppet Babies LP records produced and released on Parker Bros./Columbia records. Both albums were produced by Hank Saroyan and Rob Walsh and featured extended versions of songs from certain Muppet Babies episodes. The first album, "Rocket To The Stars" was also a fully produced stereo story-adventure starring the Muppet Babies characters in which the songs were woven into the all new story written by Saroyan. The second album was strictly more fully produced longer versions of songs from the show.

BMG released a CD version of the first album when it bought Henson.

From 1985 until 1989, Marvel Comics produced a monthly comic book of the Muppet Babies with their Star Comics imprint, drawn by Marie Severin. The series lasted for twenty-six issues. The back-up stories on the last two issues, #25 (May 1989) and #26 (July 1989), were drawn by Nate Butler. In 1992, Harvey Comics acquired the rights to produce Muppet Babies comics and produced a further 3 issues (restarting at issue #1).

The Muppet Babies also appeared in Star Comics Digest (also known as Star Comics Magazine). This comic was printed in digest size format, and features a number of reprinted short stories in each issue. The series itself lasted for thirteen issues from 1986 until 1988. It should be noted that the Muppet Babies appeared in some, but not all the issues. Other short stories contained in Star Comics Digest included Madballs, Heathcliff, the Care Bears, and Top Dog.

Although not every Muppet Babies episode was released on VHS, a number of them were released between 1993 and 1995.[citation needed] One series released on VHS called "Yes I Can" included three videos, which featured two Muppet Babies episodes inside. The series focused on Robin the Frog, who asks his uncle Kermit for assistance in different chores he was struggling with such as cleaning his room or doing homework. Kermit would lead off into a Muppet Babies episode which told of a similar situation. Sometimes, he would give examples about achieving Robin's trouble. For example, in one Yes I Can video, Robin is worried about making new friends, and Kermit tells him that sharing is an example of having a good friendship, which leads directly to a Muppet Babies episode.

A live-action version of all the characters except Skeeter also appeared in A Muppet Family Christmas in the form of a home movie, which the adult Muppets watched during the Christmas Party. The segment was cut out of the home video releases because the rights to "Santa Claus Is Coming to Town" could not be obtained.
